The effect of pH, the amount of potassium periodate and leuco-malachite green, the standing period after the color development, temperature and effects of 15 foreign ions were examined. The recommended procedure was as follows: A floating particle sample which was collected from the sea water with millipore filter was dissolved in concentrated sulfuric acid and was evaporated to dryness on a hot plate by the addition of 30% hydrogen peroxide. The residure was dissolved in water, and silica was removed by filtration. The solution is diluted to 50 ml with water, and 5 ml of acetic acid and sodium acetate buffer solution (pH 4.1), 2 ml of 10% solution of hydroxylamine hydro･chloride, and 1 ml of 0.1% solution of bathophenanthroline in ethylalcohol were added to it. Fe(2)-B.P.T. complex was extracted into 10 ml of iso-amyl-alcohol, and 2 ml of concentrated sulfuric acid was added to iron free aqueous solution. After evaporation of extracted solution the residure was diluted with water, and 0.001 μg-at.of manganese standard, 20 ml of acetic acid and sodium acetate buffer solution (pH 4.1) and 5 ml of 0.2% potassium periodate solution were added to it and allowed it to stand for 15 minutes. After addition of 2 ml of 0.04% leuco-malachite green aceton solution and dilution to 100 ml with water, the absorbance at 610 mμwas measured against the reagent blank.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学理工学部"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/23409"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025080X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学理工学部紀要. 理学編"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of Ryukyus.
